For sometime past, and even at the present time,t he`re has been' and isa vogue for eX- ceedinglyY large size vframes' forophthalmioV mountings.These are known as the shell typeframe and are usually made of a cellulose ,composition material. rlhe chief characteristic of such a mountingis its large size as comparedV with lthe usual metallic mountings' ofthe prior art. Composition frames of this ycharaeter have certaindefects that are well recognized, chief a'I'rl'ong which isthe tendencyof the material to change itsA shape 'under the influence" oftemperature changes,

The lenses are liabley to creep or turn in the lens rims,` and it ispractically impossible to ffit such a frame toy thefacia'lrequirements'o'f the wearer'. It is, therefore,` one of presentinvention to provide a metallic the objects? ofthe'` temple and endpiececonnection corresponding in size to the usual composition parts butniaintained at a minimum in weight so that the temple may be light andadjustable. At the saine time its rigidity has been maintain-ed in thebutt section adjacent the connection to the ophthalmic frame and thedesirable flexibility of metallic 'temples in the neighborhood of theear loop obtained in the structure, which was practically impossible ofattainment in the composition frames.

Referring to the drawings wherein similar reference characters denotecorresponding parts throughout, the temple 1 comprises a thin buttsection 2 which is dished in or hollowed out into a rcentrant anglecross section which is shown best in Figs. 9 and 10. This rcentrantangle cross section terminates at 3 in Fig. 1 where the cross sectionbecomes rounded or elliptical in cross section as indicated at 4l inFig. 4, terminating in the ear loop 5 and the terminal bearing button 6,which button is in the form of an open frame.

It will be seen that the butt section 2 is very rigid as to horizontaland vertical displacem-ent due to its reentrant cross section and thatthe section 4 is flexible owing to its elliptical cross section, whilethe terminal button 6 provides a wide bearing surface against the skullbehind the ear and also provides means by which the temple may be pushedthrough the hair when the frame is applied to feminine use.

The temple 1 is secured te the endpiece 7 by the hinge 8. r he hinge 8comprises a block 9, Fig. 9, having a reentrant under si de which fitsinto the reentrant portion 2 of the butt of the temple 1. The end of theportion 9 opposite the temple connection is bevelled off or pointed at10 so that it will fit into the reentrant angle of the butt 2, the sidesof the portion 10 conforming with the .sides of the reentrant angle inthe butt 2. @n the opposite end of the member 9 are the hinge ears 11.The member 9 is preferably soldered in the recntrant portion 2 of thetemple, the bevelled off end 19 forming a neat joint which blends withthe temple structure. The endpiece 7 also has hinge ears 12whichintermesh with the hinge ears 11 of the portion 9. The temple 1 issecured to the endpiece 7 by intermeshing the ears 11 and 12 and puttingthe screw 13 therethrough in the usual way.

The hinge ears 12 on the endpiece 7 may be integral therewith or may beput on a separate pad and soldered or otherwise secured thereto asdesired.

.It will be noted that the reentrant angle of the butt portion 2 of thetemple 1 has the reentrant angle on the side of the temple Which goesnext to the head. This forms a bevel on the outside of the temple havingthe facets 14 and 15, Fig. 9 and Fig. 2. The endpiece 7 is also bevelledto have the facets Lemme 16 and 17, Fig. 1, which blend with the facets141 and 15 of the temple 1 so that the central line of the temple and ofthe endpiece form one continuous line. The hinge end of the temple andthe endpiece are bevelled as indica-ted at 18 in Fig. 8 to provide astop so that the movement of the temple about the hinge will be limitedto ninety degrees when `the temple is extended from the frame.

By reference t0 Fig. 1 it will be seen that the cross section of theendpiece 7 is variable. Fig. 11 shows the cross section on line 11-11 ofFig. 1 having a fiat surface 23 on the face side and the -facets 16 and17 on the outside. On line 1212, Fig. 1 `the cross section is as shownin Fig. 12 having a fiat side 23 on the inside and the facets 16 and 17on the outside and additional facets 24e and 25 while Fig. 13 shows across section on line 18-18 of Fig. 1 containing a flat portion 23 onthe inside and the facets 24 and 25 on the outside.

It will be seen from Fig. 9 that the lens rim 26 has a. Vshaped groove27 on the inside for the lens, the rim being also of V-shape on theoutside, and that in joining the endpiece 7 to the rim 26 the end of theendpiece which adjoins the frame is bevelled along the line 28 to form astructure which will blend in the facets 0f the endpiece with the rim.

In producing the temple I proceed as follows: I take a bar of material19 as shown in Fig. 5 and swage or flatten out the butt portion 20, asshown in Fig. 5, leaving the rounded portion 19 and reducing the earloop end as at 21. I next swage or press in the reentrant angle 2 in thesection 2O as shown in Fig. 7 blending this portion in with the section19 and reducing the section 19 to an elliptical cross section as shownin the cross section in Fig. 7. I next bend up the end of the port-ion21 to form 'the tip pad 6 soldering in the end at 22, Fig. 4. ThereafterI bend the end 21 to form the ear loop 5, Fi Ll. Then the block 9 havingbeen fashioned with its pointed end 10 and provided with the hinge ears11 is placed in the reentrant angle 2 at the end thereof and soldered inplace as indicated 'in Fig. 9. The endpiece of the mounting haspreviously been fashioned with the hinge ears 12. The ends of theendpiece 7 and the temple 1 are bevelled off as at 18, Fig. 8; 'the ears11 and 12 are pla-ced in intermeshing relation, and the pivot screw 13is inserted therethrough as indicated in Fig. 9

From the foregoing description the construction and operation and theprocess will be apparent, and it will be seen that I have provided in aunit-ary construction, simple, efficient and economical ways ofproducing a temple, producing a light weight temple of relatively largedimensions having a rigid butt section, a flexible section adjacent theear portion With broad bearing surfaces at the end of the ear loop Whichmay be easily entered through the hair When intended for feminine use,producing a structure Well adapted to carry out all the advantages setforth, as Well as others.

Having described my invention, I claim: l. A temple connection for anophthalmic mounting comprising a temple member having a substantiallyV-shaped dished cross section, a hinge member having a V-shaped bodyportion to fit into the recess of the V-shaped dished temple crosssection and a bevelled end portion opposite the hinge connection end totaper off the joint With the temple, and having a projecting hingeconnection for pivotally supporting a temple.

2. A temple connection for an ophthalmic mounting comprising a templemember having a concavo-'convex cross section, a hinge member having abody portion to fit into the recess of the concavo-convex cross sectionof the temple and its end farthest removed from the hinge connectionbevelled to taper off the l joint with the temple, and having aprojecting hinge connection for pivotally supporting a temple.

3. A temple connection for an ophthalmic Y mounting comprising a templemember having a dished V-shaped cross section, the apex of the V beingon the outer side thereof and forming a straight longitudinal linecentrally of the temple, a lens rim member having an endpiece for thetemple connection having a V-shaped cross section, the apex line of theV aligning with the apex line of the V of the temple and forming acontinuation thereof, and interengaging hinge members on the temple andendpiece hingedly connecting the two.

4; A temple connection for an ophthalmic mounting comprising a templemember having a dished V-sha ed cross section, the apex of the V beingon t e outer side of the temple and forming a straight longitudinalline. centrally of the temple, a lens rim member having an endpiece forthe temple connection having a V-shaped cross section, the apex line ofthe V aligning with the apex line of the V of the temple and 'forming acontinuation thereof, and V-shaped facets between the V- f shaped crosssection of the endpiece and the Y rim, the apex line of Which forms acontinuation of the apex line of the temple and endpiece, andinterengaging hinge members on the temple and endpiece hingedlyconnecting the two.
